A novel metallocene catalyst for the polymerization of olefin (co)polymers is of the general formula: Benzothiazole-E-M-XmLn where, M is a transition metal of Groups 3-10 of the Periodic Table; E is sulfur or oxygen; E being bond to the transition metal and to the carbon atom between sulfur and nitrogen of the benzothiazole moiety; L is a polymerization-stable anionic ancillary ligand; X is a halogen, alkoxy from C1 to C20, siloxy from C1 to C20, N(R1)2, a hydrocarbyl group containing up to about 12 carbon atoms or hydrogen or mixtures thereof; preferably X is halogen, methoxy, ethoxy or siloxy (R1)3SiO- , where R1 is alkyl from C1 to C20; and m+n equals the valency of the M minus 1.
L'invention porte sur un nouveau catalyseur métallocène utilisé dans la polymérisation de (co)polymères oléfiniques et ayant la formule générale: Benzothiazole-E-M-XmLn dans laquelle M est un métal de transition des groupes 3 à 10 du tableau périodique; E est soufre ou oxygène; E étant lié au métal de transition et à l'atome de carbone entre soufre et azote et la fraction benzothiazole; L est un ligand ancillaire anionique stable à la polymérisation; X est un halogène, alcoxy de C¿1? à C¿20?, siloxy de C¿1? à C¿20?, N(R¿1?)¿2?, un groupe hydrocarbyle contenant jusqu'à environ 12 atomes de carbone ou hydrogène ou des mélanges de ceux-ci; de préférence, X est halogène, méthoxy, éthoxy ou siloxy (R¿1?)¿3?SiO-, où R¿1? est alkyle de C¿1? à C¿20?; et m+n est la valence de M moins 1.
